Scientific Car Maintenance Guide: Key Practices to Extend Your Vehicle's Lifespan

Car maintenance is a systematic process to maintain optimal vehicle performance, ensure driving safety, and extend its service life. Scientific maintenance not only prevents malfunctions but also significantly reduces long-term repair costs. Core maintenance items primarily include: 1. Engine Oil and Oil Filter: The "lifeblood" of the engine. It is recommended to change them every 5,000 to 10,000 kilometers or every six months. High-quality engine oil effectively reduces engine wear and improves fuel economy. 2. Air Filter, Cabin Air Filter, and Fuel Filter (collectively known as the "Three Filters"): Require regular inspection and replacement, typically every 10,000 to 20,000 kilometers. Clean filters ensure clean air intake and fuel, directly impacting engine power and in-cabin air quality. 3. Tire Maintenance: Check tire pressure (including the spare tire) monthly to ensure it meets the standard value. Also, monitor tire wear; tires must be replaced when the tread depth falls below 1.6 mm. Perform wheel alignment and balancing every 10,000 to 20,000 kilometers. 4. Braking System: Regularly inspect brake pad thickness and brake fluid condition. Brake pads must be replaced immediately if the remaining thickness is less than 3 mm. Brake fluid is typically replaced every 2 years or 40,000 kilometers. 5. Battery and Various Fluids: Monitor battery lifespan (generally 2-4 years) and regularly check the level and quality of coolant, transmission fluid, power steering fluid, etc. Furthermore, follow the official interval recommendations in the Vehicle Maintenance Manual and consider shortening maintenance intervals based on actual driving conditions (e.g., frequent short trips, harsh road conditions). Maintaining complete service records helps accurately understand the vehicle's condition and can enhance its residual value during resale. Cultivating the habit of regular professional inspections, allowing preventive maintenance to replace reactive repairs, is a wise choice to ensure safe and smooth journeys for you and your beloved vehicle.
